The ADV212 can process images at a rate of 40 MSPS in
reversible mode and at higher rates when used in irreversible
mode. The ADV212 contains a dedicated wavelet transform
engine, three entropy CODECs, an on-board memory system,
and an embedded reduced instruction set computer (RISC)
processor that can provide a complete JPEG2000 compression/
decompression solution.
The wavelet processor supports the 9/7 irreversible wavelet
transform and the 5/3 wavelet transform in reversible and
irreversible modes. The entropy CODECs support all features
in the JPEG2000 Part 1 specification except maximum shift
region of interest (ROI).
The ADV212 operates on a rectangular array of pixel samples
called a tile. A tile can contain a complete image, up to the
maximum supported size, or some portion of an image. The
maximum horizontal tile size supported depends on the wavelet
transform selected and the number of samples in the tile.
Images larger than the ADV212 maximum tile size can be
broken into individual tiles and then sent sequentially to the
chip while maintaining a single, fully compliant JPEG2000 code
stream for the entire image.

JPEG2000 FEATURE SUPPORT
The ADV212 supports a broad set of features that are included
in Part 1 of the JPEG2000 standard (ISO/IEC 15444).
Depending on the particular application requirements, the
ADV212 can provide varying levels of JPEG2000 compression
support. It can provide raw code block and attribute data
output, which allows the host software to have complete control
over generation of the JPEG2000 code stream and other aspects
of the compression process such as bit-rate control.
Additionally, the ADV212 can create a complete, fully
compliant JPEG2000 code stream (J2C) and enhanced file
formats such as JP2.
